Predict the co-ordination number in [Pt (OH)2 (NH3)4] SO4.
Correct answer: C. 6
- A. 4
- B. -4
- C. 6
- D. 2
Explanation
The number of lone pair of electrons provided by the ligands to the central metal atom or ion is called the coordination number of the central metal atom or ion.In this complex, both NH3 and OH are monodentate ligands (meaning they donate single electron pair) and there are 2 OH groups attached to central atom and 4 amino (NH3) groups attached so coordination number is 2+4=6.

About Electronic Structure of d-Block Elements
The electronic structure of d-block elements covers the filling of the (n-1)d and ns orbitals, general electronic configurations, and the exceptions shown by chromium and copper. It explains how partially filled d orbitals produce variable oxidation states, coloured ions, magnetic behaviour and complex formation, while distinguishing transition elements from elements with completely filled d subshells.
